I'm in need of help with an Halo 3 problem ?

Question

Every time I log onto XBox Live to play Halo 3 online I get into the lobby, I get put into a game each time, and when we get partied up and all of a sudden I'm back in the lobby. I tried this a few more times just to see what would happen and each time the same thing. It's really getting on my nerves and I'd like to know what's wrong.

Answer 1

It could be you internet connection. Try restarting your modem or make sure you have an open NAT. Also make sure you Xbox Live Gold subscription is not expire.  

Answer 2

It happens once in a while, it's been happening to me lately too. Is your NAT open?

Answer 3

Try deleting the Halo 3 system data from you Xbox, this will be in your memory, don't be scared... trust me, lol. Then pop halo 3 back in get on-line and it will make you re-download some stuff, your game should work!

You will lose screen shots and replays that are saved to your box, anything saved to your profile will be kept at bungie.
